DOVER — The price of a cup of lemonade has increased over the years, but the generosity behind the sweet drink seems to be growing — at least for the glasses served at 18 Philip St. last weekend.

Grace Bonyman and Tylee Barnes, both 9, of Dover, hopped off the school bus last Friday and decided to have a lemonade stand. Each plastic cup of lemonade was served with a lilac freshly picked in Grace's backyard by the two young girls.

Purchasers were also told that their dollar for the flower and beverage was not going into their piggy banks, but was going to be donated to the One Fund, to support the victims of the Boston Marathon bombings last month.

After a couple hours Friday night, Grace and Tylee had made more than $32.

“I am so proud of them,” Grace's mother, Kristie Bonyman, said. “I actually feel like a negative Nelly, I thought at first that they were never going to make any money.”

Kristie said she left to go grocery shopping during the time the girls were hosting the lemonade stand and when she returned home, the girls were beaming with joy, shouting how they had made more than $20 for the victims.

“They were so proud of themselves for having all this money,” Kristie said.

To top it off, at the end of the night, Grace and Tylee brought the remaining lemonade and extra flowers to one of Grace's neighbors, who is handicapped.

The neighbor was grateful for the special surprise, but told the girls that since they gave to her, she was going to give to their cause. She donated $10, according to Kristie.

“The really beautiful thing was just the generosity of my neighbors,” Kristie said, adding that the mail carrier donated without taking any lemonade and one person took a glass, but gave the girls extra money.

Grace found out about the bombings at the Boston Marathon last month at the same time her mother did. Kristie said they watched the news together.

“It's very confusing for a child, what is happening and why,” she said. “When (Grace) saw that a young boy was killed (Martin Richards), that really hit home for her. She said, 'That could've been a boy in my class.'”

Kristie said that when the girls decided to have the lemonade stand to give back to the Boston victims, they specifically said they wanted to help people who lost their legs so they could walk again.

Kristie will be bringing Grace and Tylee to TD Bank later this week to give their donations to the One Fund. Kristie said that if anyone would also like to contribute, they can send their money to her home at 18 Philip St., or stop in a TD Bank, which is collecting donations for the One Fund.
